GISP Practice Exam Questions and Answers Already Passed

GISP Practice Exam Questions and Answers Already Passed The property of area for a parcel polygon may be considered this: Precise and accurate A vector data model uses which of the following coordinate pair types to build curvature within a line? Points GIS differs from surveying and mapping by introducing this: Spatial analysis The mathematical model related to real world features Datum Which method is used to align an unreferenced dataset with one that has spatial reference information? Georeferencing Common locations used in aligning two datasets Control points In a map showing contours, the name of the darker contour line Index contours imaginary lines on a map that represent areas of constant elevation Contours The inherent ability to suggest pattern in the phenomena they represent is a fundamental use of these Maps If you are making a web map of sampling locations, streams and watershed areas, in what order would you place the layers on the map Sampling locations, streams, wetland areas A small-scale map would show this Larger geographic area data format that would most likely represent a file exported from AutoDesk-AutoCAD .DXF Create database security settings which reflect the needs of the organization, Create queries for reporting purposes, Backup and Recovery of database Roles of database administrator GIS requires heavy CPU usage, GIS services sometimes transmit large images, Clients of GIS services are often complex software packages characteristics of GIS services that make it difficult to design GIS web services with satisfactory performance Leveraging GIS to support an enterprise environment can be best accomplished using this approach Geospatial data served as map services and web maps The database will contain many GIS layers, each with an associated attribute table. In addition, other tables may exist that further describe specific characteristics of the GIS layer and are associated with the GIS layer through a relationship. Each table may contain numerous fields (attributes). object-relational databases technology that allows for multiple server instances on a single piece of hardware/single server virtualization NOT a true relational database Access overlay analysis is based on this Boolean logic the most basic skills in the world of programming scripting and tool modification 45 degrees π/ 4rad = Filtering data based on the specific content stored in a field refers to Attribute query The shapefile format is a digital vector format for storing geometric locations and associated attribute information. While it can consist of several files with different file name extensions, three file names are needed to be properly identified as a shapefile shp, shx, dbf Calculations (sum, average, median, etc.) can't be performed on this type of field character When converting Degrees/Minutes/Seconds of latitude in the Northern Hemisphere to decimal degrees Divide the Seconds by 3600, divide the Minutes by 60, then add those values to the degrees, i.e. (Deg+(Min/60)+(Sec/3600)) If converting Degrees/Minutes/Seconds of latitude in the Southern Hemisphere to decimal degrees, what would change from question 39? You would multiply the derived value by -1 How would you determine the horizontal accuracy of an ortho-rectified aerial image Photo-identifiable field points are surveyed and the Root-Mean Square error between the image and the PhotoID points is computed the most common statistical method to determine the attribute (land classification) accuracy of a raster- derived land use/land cover map Compute a Confusion Matrix based on ground truthing a stratified random sample of polygons The Federal Geographic Data Committee has endorsed this the CSDGM, ISO 19115, and additional ISO metadata standards used to extract features and their attributes from one layer using a polygon from another as the boundary of the output clip used to build new features by splitting overlapping features and combing attributes where the features overlap union appends together layers of adjoining area merge Determining which background data shown on the paper maps is the most accurate to use in georeferencing it; Ability to understand the notations made and to interpret the attributes for each feature important considerations when converting hand-drawn features from a hard copy map to digital GIS data Using templates or prescribed schemas for feature creation to ensure data quality; The capabilities of the GPS receiver and alignment of GPS satellites at the moment the data is collected When collecting GPS data, what are the most important factors in determining the accuracy of the resulting data?
